The research proposes a variable‐speed fixed‐displacement pump control strategy combined with a fuzzy PID algorithm. A co‐simulation model is developed, key parameters are set, and comparative energy consumption analyses are conducted between the variable‐speed fixed‐displacement pump and the fixed‐speed variable‐displacement pump through simulation ...

ABSTRACT With the development of wind turbines to deep sea, its working environment is more and more severe, which puts higher stability requirements of the transmission chain. A variety of front‐end speed regulation methods have been proposed because this method can improve the reliability of wind turbines by eliminating electrical components with ...

Model‐Based Exploration of Web Guiding Behavior for a Novel Battery Cell Stacking Process
The modeling of new processes and machines enables a rapid ramp‐up of often untested or immature technologies. The exact guidance of electrode webs is an important process step for robust production. Herein, a model for the web guidance of electrodes is integrated into an overall machine model for a new stacking technology.

Analysis of Influence of Control Valve Structure on Fuel Injection Performance of an Injector
ABSTRACT On the basis of the structure of the traditional electromagnetic injector, this paper proposes a new type of electromagnetic injector structure by changing the opening mode of the control valve. Taking the fuel injection consistency and response time as the evaluation indexes, a one‐dimensional simulation model was established to compare the ...
